He wrote a great book called Travels and Adventures of Alexander Henry. In it, he describes the massacre at Michilimackinac during the Pontiac Rebellion; his life was spared by Wawatam, an Algonquin Indian who had adopted Henry as his brother. Henry lived with Wawatam's family for a year, then, as Pontiac's rebellion was suppressed, he returned to being a fur trader.

In later years Henry was a founding member of the Beaver Club in Montreal -- an association of Canadian trappers, voyageurs, and traders.

His nephew, also named Alexander Henry and also a fur trader in the same area, kept a monumental journal. Henry the Younger was an odd fish - he doesn't write with the same genial personality as his uncle, but comes off as cold and unfeeling. But his journal tells a detailed story of the life of a trader and of the decimation of the surrounding Native American tribes by disease and alcoholism.

The journal of Henry the Younger fascinatingly describes many of the same people who are in the tribe that adopted John Tanner, a white man who grew up with the Ojibwa and later recorded his life story.

Even in contemporary sources, it is easy to confuse the two Alexander Henrys, both well-known traders and explorers based in Montreal. Between their two journals, I would recommend Travels and Adventures as a good read -- really an adventure story.
